[英]C reading struct from text file
I have an array of structures stored as text;我有一个存储为文本的结构数组; each array item begins with a number followed by a closing bracket, followed by the data for each struct member on a line on its own.每个数组项以一个数字开头,后跟一个右括号,后跟每个结构成员的数据单独一行。 For example例如
1)
Andrew
Bilous
Andriyovuch
director
1
1000
2)
... and so on...
Can you help me to write a loop that will read each one into a single array of structures你能帮我写一个循环,将每个循环读入一个结构数组吗
struct spivrob {
char *name;
char *surname;
char *pobat;
char *posada;
int staz;
int oklad;
} tab[6];
FILE *fo;
fo = fopen("C:\\Users\\andyb\\Desktop\\test7.txt","r");
I've not tested this, other than to check it compiles, but it should do the trick我没有测试过这个,除了检查它编译之外,但它应该可以解决问题
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char* initAndGetNextLine(FILE* fo, size_t length);
int getNextLineLength(FILE* fo);
int main()
{
struct spivrob {
char *name;
char *surname;
char *pobat;
char *posada;
int staz;
int oklad;
} tab[6];
FILE *fo = fopen("C:\\Users\\andyb\\Desktop\\test7.txt","r");
char* line = NULL;
size_t length = 0;
int i = 0;
int j = -1;
while(!feof(fo) && !ferror(fo)) {
int len = getNextLineLength(fo);
char* newString = (i %7 < 5)? initAndGetNextLine(fo, len) : NULL;
switch(i % 7) {
case 0: j++;
case 1: tab[j].name = newString; break;
case 2: tab[j].surname = newString; break;
case 3: tab[j].pobat = newString; break;
case 4: tab[j].posada = newString; break;
case 5: tab[j].staz = atoi(line); break;
case 6: tab[j].oklad = atoi(line); break;
}
i++;
}
}
int getNextLineLength(FILE* fo)
{
char c;
int i = 0;
do {
c = fgetc(fo);
i++;
} while(c != '\n' && !feof(fo) && !ferror(fo));
fseek(fo, -i, SEEK_CUR);
return i;
}
char* initAndGetNextLine(FILE* fo, size_t length)
{
char* newString = malloc(length * sizeof(char) + 1);
fgets(newString, length, fo);
newString[length] = '\0';
return newString;
}
